Chapter 3: Audio Connections 17
Additional I/O Connectors
Control|24 provides the following individual
connectors on the back panel:
Input
MIC and LINE Inputs
These 16 balanced connec-
tors (XLR for Mic inputs, TRS for 1/4-inch in-
puts) are the inputs to the Control|24 mic
preamps. Levels are adjustable with a dedicated
Gain control on the Control|24 channel strips.
(MIC and LINE inputs are output through the
Control|24 LINE OUTS 1–8, and LINE OUTS
9–16.)
D.I. INPUTS
These two balanced, 1/4-inch input
jacks accept instrument-level inputs and are op-
timized for direct input of guitars, basses, and
other low-level devices that would otherwise re-
quire a direct box. These inputs can only be used
as Instrument inputs for Control|24 mic preamp
channels 1 and 2.
AUXILIARY INPUTS
These two balanced, line-
level TRS inputs are for cue (headphone) mix
signals, and should be connected to your
Pro Tools cue outputs (usually, a pair of audio
interface outputs carrying a Send-based cue mix,
for monitoring during overdubbing and track-
ing). These inputs can be controlled and routed
in the Communications and Headphones sec-
tion.
EXTERNAL TALKBACK IN
This XLR connector
lets you connect an external microphone to use
in place of the built-in Talkback mic.
EXTERNAL LISTENBACK IN
This XLR connector
lets you connect an external Listenback micro-
phone, to provide a way for two-way communi-
cation between the tracking room and the con-
trol room.
Output
AUXILIARY OUTPUTS
These two balanced, line-
level TRS outputs are for cue mixes, and should
be connected to the inputs of your cue system.
SUBMIXER OUTPUTS
These two line-level, bal-
anced TRS outputs carry the submix from the
LINE SUBMIXER. The LINE SUBMIXER output is
only accessible through the SUBMIXER OUT-
PUTS (in other words, the Line Submixer is not
mixed or routed to any other Control|24 inter-
nal busses or hardware outputs).
SLATE OUTPUT
This balanced TRS connector
outputs the Control|24 Slate output, which can
include Talkback and Listenback signals. Con-
nect this output to an available Pro Tools input
for recording slates (take number, version num-
ber, and studio communication).
Other Connectors and Switches
Footswitch Inputs Provide footswitch control for
Pro Tools transport functions (such as
play/stop, and punch in/out), and Talkback.
Function and polarity are individually selectable
for each input.
Ethernet Provides an Ethernet connection be-
tween Control|24 and your computer.
Power Accepts a standard AC power cable, and is
auto-switching for use in any country.
Switches
Power Turns Control|24 on or off.
Phantom Power Two switches that 48v
phantom power to their corresponding bank of
eight mic preamp channels (Switch 1 affects
preamp channels 1–8, and Switch 2 affects
preamp channels 9–16.)
